Abstract: A method may include receiving a domain name system (DNS) query at a network device, where the DNS query may be associated with a traffic flow identified for rerouting through an alternative path utilizing an alternative network device instead of a default path. The method may also include rewriting the DNS query such that the DNS query is routed through the alternative network device along the alternative path and to a DNS server associated with the alternative path. The method may additionally include receiving a DNS response from the DNS server, where a resource identified in the DNS response may be based on the DNS query coming through the alternative network device.
